The single-camera comedy centers on nemeses Grace (Fonda) and Frankie (Tomlin), whose lives are turned upside down when their husbands announce they are in love with each other and plan to get married. The women, much to their dismay, find that their lives are permanently intertwined and, much to their surprise, find they have each other.

Stults will recur as Mitch, Mallory's (Brooklyn Decker) husband of seven years. The character is an OBGYN and father of two who is always on call and trying to do the best he can with juggling his husband/father and doctor duties. Stults, who most recently starred in CBS' comedy pilot Cuz-Bros, toplined Fox's short-lived critical darling Enlisted. The comedy remains in contention for a second season at Yahoo Screen. Stults is repped by UTA and Thruline.

Morton will appear as Jason, one of Frankie and Sol's (Sam Waterston) oldest, dearest friends. In future episodes he will not only help Frankie navigate the world of divorce, but he will also help Sol grow more comfortable being "out." Morton, who is poised to return to Scandal during its upcoming fourth season, will next co-star in TNT's new drama series Proof. He's repped by TalentWorks and Vanguard Management.

Bostwick is set as Bill, an old friend of Grace and Robert's (Martin Sheen) who is also newly divorced and knows exactly what Grace is going through. The question is: Could he be the answer to her problems? The role marks a reunion with Stults and Morton after Bostwick guest-starred on Fox's Enlisted and ABC's Scandal, respectively. (Yes, Scandal fans, Fitz's father and Olivia's dad are both going to be on the new Netflix comedy.) He's repped by TalentWorks and Vanguard Management.

Grace and Frankie is slated for a 2015 debut and is written and created by Friends co-creator Marta Kauffman and Howard J. Morris (TBS' Sullivan & Son, According to Jim, Home Improvement). Kauffman, Morris, Paula Weinstein, Fonda, Tomlin and Skydance's David Ellison, Dana Goldberg and Marcy Ross are on board to executive produce. Tate Taylor (The Help) also serves as executive producer and will direct the first episode.
